Hello,
I am not sure however, Windex does have Ammonia in it. Use some type of Auto polish. It is much cheaper than guitar products and protects finishes the same way.
Warm water and mild soap is the trick.
Pledge has some wax in it, you'll just add a layer of potentially sticky stuff. I remember the wood furniture when I was a kid, it was Pledged every week and man did it becomme sticky. My mom had to strip it ever so often, with ammonia or something.
